Tab. 4 Approved Flue gas or combustion air materials and ttings per boiler
1 PVC must not be used for vent material when a glycol mixture is used in the boiler circuit.
2 Components of the certied vent systems must not be interchanged with other vent systems or unlisted pipe ttings. Plastic components, and specied
primers and glues of the certied vent system must be from a single system manufacturer and not intermixed with other system manufacturer’s vent
system parts. For installations in Canada, eld supplied plastic vent piping must comply with CAN/CSA B149.1 (latest edition) and be certied to the
Standard for Type BH Gas Venting systems. ULC S636.
The supplied vent connector and separate available vent terminations are certied as a part of the boiler.
Standard straight pipes, 90°-elbows or Tees are approved as roof or wall terminations in all the approved materials. Furthermore the following terminations
